i'd like to create a custom effect for the transparency-calculations. my idea is to split the calculation into different angles. say for example if the refraction index is 1.5 than the red color is calculated with 1.4 and the blue with 1.6

but i dont have a clue how or where to start so i'd be thankfull if anyone can point this out to me. which of the examples in the sdk folder could be a starting point for such a shader?

thanks for your help

a good starting point is the mandelbrot shader example and the simple material example because that shows how to use custom illumination models. besides this there is alot of info on the web about shading in general.

cheers,

But in those examples there is nothing about transparency channel. I'm looking for any example who explains how to manipulate with refraction index (and i didn't find in sdk anything).

Have you got sth? Part of code, or link to web tutorial;) ?
